1. Precautions and Safety Notices
1-1. Appropriate Operation
(1) Turn off the product before cleaning.
(2) Use only a dry soft cloth when cleaning the LCD panel surface.
(3) Use a soft cloth soaked with mild detergent to clean the display housing.
(4) Use only high quality and safety approved AC/DC power adapter.
(5) Disconnect the power plug from AC outlet if the product is not used for a long period of time.
(6) If smoke, abnormal noise or strange odor is present, immediately switch the LCD display off.
(7) Do not touch the LCD panel surface with sharp or hard objects.
(8) Do not place heavy objects on the LCD display, video cable, or power cord.
(9) Do not use abrasive cleaners, waxes or solvents for your cleaning.
(10) Do not operate the product under the following conditions:
- Extremely hot, cold or humid environment.
- Areas susceptible to excessive dusts and dirt.
- Near any appliance generating a strong magnetic field.
- Place in direct sunlight.
1-2. Caution
No modification of any circuit should be attempted. Service work should only be performed after you are
thoroughly familiar with all of the following safety checks and servicing guidelines.
1-3. Safety Check
Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit,
the voltage is exposed in such areas as the associated transformer circuits.
1-4. Power Supply Requirements
The external power converter for this display utilizes AC and DC cords, AC cord is detachable, but DC cord is
permanently attached. Any attempt to replace another adapter could result in serious problem on the
display.

1-5. LCD Module Handling Precautions
1-5.1 Handling Precautions
(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when inserting or disconnecting from input connector.
(3) Wipe off water drop immediately. Long contact with water may cause discoloration or spots.
(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
(6) Since CMOS LSI is used in this module, take care of static electricity and insure human earth when handling.
(7) Do not open nor modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module to any directions.
(9) In case if a Module has to be put back into the packing container slot after once it was taken out from the
container, do not press the center of the CCFL Reflector edge. Instead, press at the far ends of the CFL
Reflector edge softly. Otherwise the TFT Module may be damaged.
(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt the Interface
Connector of the TFT Module.
(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for example), do not twist nor
bend the TFT Module even momentary. At designing the enclosure, it should be taken into consideration
that no bending/twisting forces are applied to the TFT Module from outside. Otherwise the TFT Module
may be damaged.
(12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow local ordinances
or regulations for disposal.
(13) Small amount of materials having no flammability grade is used in the LCD module. The LCD module
should be supplied by power complied with requirements of Limited Power Source (IEC60950 or UL1950),
or be applied exemption.
(14) The LCD module is designed so that the CFL in it is supplied by Limited Current Circuit (IEC60950 or
UL1950). Do not connect the CFL in Hazardous Voltage Circuit.

4. Circuit Description
1. WORKING THEOREM
A. Scaler
The RTD2023 is total solution graphics processing IC for LCD monitors with panel resolutions up to SXGA. It is configured with integrated 8-
bit triple-ADC/PLL, a high quality display processing engine, and an integrated output display interface that can support Dual / Single LVDS
panel interface format. To further reduce system costs, the RTD2023 also integrates intelligent power management control capability for
green-mode requirements and spread-spectrum support for EMI management. The RTD2023 incorporates the world's first coherent
oversampled RGB graphics ADC in a monitor controller system1. The oversampling ADC samples the input RGB signals at a frequency that
is much higher than the signal source pixel rate. This can preserve details in the video signal that ordinarily would be lost due to input signal
jitter or bandwidth limitations in non-oversampled systems.
B. MCU:
The MTV512M micro-controller is an 8051 CPU core embedded device especially tailored for flat panel display application. It
includes an 8051 CPU core, a 768K-byte SRAM, 4 channels of 6-bit ADC,3 external counters / timers ,6 channels of PWM
DAC,VESA DDC interface, and a 64k-byte internal program Flash-ROM memory. of 6-bit ADC, and a built-in , It also includes two
IIC Slave B ports, supporting VESA DDC/CI for D-sub interfaces, and a Boot-Code-Free ISP (In System Programming).

5-1.5.2 Auto Image Adjust
Please select and enter "Auto Adjust" function on Main Menu to
see if it is workable. The "Auto Adjust" function is aimed to offer
a better screen quality by built-in ASIC. For optimum screen quality, the
user has to adjust each function manually.
5-1.5.3 Firmware
Test Pattern: Burn in Mode (Refer to Chapter III-3. Hot Keys for Function
Controls) - Make sure the F/W is the latest version.
5-1.5.4 DDC

5-1.5.5 Fine Tune and Sharpness
Test Signal: 1280 x 1024 @ 60.0kHz
Test Pattern: Line Moiré Pattern
- Check and see if the image has noise and focus performs well. Eliminate
visual line bar.
- If not, readjust by the following steps:
(a) Select and enter "Auto config" function on "Auto Adjust" to
adjust the image to eliminate visual wavy noise.
(b) Then, select and enter "Sharpness" function to adjust the clarity and
focus of the screen image.

- Check and see if there are dead pixels on LCD panel with shadow gauge
and filter film.
- The total numbers and distance of dead pixels should be compliant with the
spec.
5-1.5.10 Mura
Test Pattern: White, RGB, Black, & Grey
Test Tool: 10 % ND Filter
- Check if the Mura can pass 10 % ND Filter.

832*624@75Hz, 1024*768@50/60/70/72/75/85Hz;
1280*1024@60/75Hz
- Normally when the primary mode 1280*1024@60Hz is well
adjusted and compliant with the specification, the secondary display
modes will be great possible to be compliant with the spec. But
we still have to check with the general test pattern to make sure
every secondary is compliant with the specification.
5-1.5.12 All Modes Reset
After final QC step, we have to erase all saved changes again and restore
the factory defaults. You should do "All Mode Reset" again.
